Despite lacking a strong business model (outside of premium themes and listings that is), Tumblr’s interest from investors is probably due to the micro blogging site’s skyrocketing rise (at the expense of Typepad nonetheless).

The company also boasts a high retention rate for users (up to 80%), with the site is quickly gaining the attention of celebrities, one who (more or less) ditched Twitter and asked his followers to embrace Tumblr instead.

Tumblr thus far has declined to publicly disclose the size of the investment (although we will update the post if we hear any figures), although whatever the figure it should be enough to keep the lights on long enough for the company to figure out a way to become profitable in the not so distant future.
